Seabound is a climate tech startup that builds carbon capture equipment for ships. New regulations from the International Maritime Organization require ships to slash CO2 emissions by 40% by 2030, but emerging clean technology such as hydrogen and ammonia are still 10-20 years away from maturity. Ship-based carbon capture has the potential to rapidly decarbonize shipping because it leverages land-based technology and can be retrofitted onto existing ships. Seabound's equipment sits adjacent to a ship's funnel and traps up to 95% of the CO2 from its exhaust, using patent-pending technology. Once the ship is back in port, the CO2 is offloaded and post-processed before being sold for utilization (e.g. electro-fuels) or for sequestration.
